ADUM242E1BRIZ-RL

Overview

The ADUM242E1BRIZ-RL is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation with a data rate of 150Mbps and common-mode transient immunity of 75kV/µs. The device features unidirectional channels in a 2:2 configuration within a 16-SOIC package. Operating voltage ranges from 1.7V to 5.5V, with a maximum propagation delay of 13ns and pulse width distortion of 3ns. It operates between -40°C and +125°C.

Feature Summary

• Integrates four independent signal paths using proprietary iCoupler magnetic coupling for robust galvanic isolation.
• Provides high common-mode transient immunity to reject noise spikes across the isolation barrier.
• Supports wide supply voltage operation compatible with various logic families without level shifting components.

Applications

• Industrial automation control systems requiring isolated communication interfaces
• Medical equipment needing reinforced isolation for patient safety compliance
• Power electronics gate drive circuits for monitoring and feedback signals

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Check current availability status as supply constraints may affect lead times. Ensure storage conditions comply with moisture sensitivity level requirements before reflow soldering. Confirm pinout compatibility with existing PCB layouts during integration planning.

Selection Notes

Select this model when four isolated bidirectional channels are required within a single package. Consider the 150Mbps speed limit for high-frequency applications. Evaluate thermal performance given the SOIC-16 package constraints. Compare against ADUM242D variants if different channel configurations or specific timing characteristics are needed for the design.

Part Context

Part of the ADuM240/242 series featuring CMOS-based iCoupler technology. Designed for general-purpose digital isolation replacing traditional optocouplers. Offers superior reliability and consistency compared to optical devices. Integrates on-chip transformers for efficient signal transmission across the isolation barrier.

Replacement Considerations

ADUM242D1BRIZ-RL offers similar functionality with potentially different timing specifications. ADUM242E0BRIZ-RL provides an alternative configuration within the same family. Verify electrical parameters and pinout compatibility before substitution. Consult official documentation for detailed cross-reference information.
